采用单因素试验方法，研究了不同养殖密度对半滑舌鳎生长的影响。试验设置400、500、600尾/池三种养殖密度梯度，选择同源、同批次且体重均为600 g左右的半滑舌鳎成鱼在闭合式循环养殖系统中养殖153 d。结果表明：不同养殖密度对半滑舌鳎体重的增长有显著影响（P＜0.05），低密度组、中密度组和高密度组半滑舌鳎的体重平均增长量分别为671.35 g、650.94 g、474.07 g，高密度组显著低于低、中密度组（P＜0.05）。随养殖密度的增大，半滑舌鳎的生长呈现减慢的趋势，并且出现了生长离差。分析表明，500尾/池的养殖密度在实际养殖生产中较为适宜。结果提示，养殖密度是影响半滑舌鳎生长的一个重要因素，过高的密度会抑制半滑舌鳎的生长。

Based on the single factor experiment method, it is studied the effects of different stocking densities on the growth of tongue sole. The experiment set up three density gradients with 400, 500, 600 tails per pool, respectively. The adult tongue soles with the homologous, the same batches and the weight of 600 g approximately were fed in the closed recirculating aquaculture system for 153 days. The results show that different stocking densities had a significant effect on the growth of tongue sole(P<0.05). The average weight growth of low density, medium density and high density group of tongue sole was 671.35 g, 650.94 g, 474.07 g, repectively, and the average weight growth of high density group was significantly lower than that of low, medium density group(P<0.05). With the increase of stocking density, the growth of tongue sole showed the slowing trend and the growth deviation. The analyses show that the stocking density of 500 tail per pool is appropriate in the actual production . The results suggest that the stocking density is an important factor affecting the growth of tongue sole, and too high density can inhibit the growth of tongue sole.
